From: Dong Zhou Date: Tue, 19 Jan 2021 03:39:39 +0000 (+0200) Subject: app/flow-perf: split dump functions X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d8099d7ecbd05813e31bb32180e8f3bc898c5688;p=dpdk.git app/flow-perf: split dump functions The app will calculate and output used CPU time for flow insertion rate. It's also needed for some new insertion items, such as meter. It's better to split this calculation and output part to a single function, so that all new insertion items can use it.
